Question：Can you tell me about the great scientist Qian Xuesen?

Great Scientist——钱学森先生

    Qian Xuesen, a former Caltech rocket scientist who helped establish the Jet Propulsion Laboratory before being deported in 1955 on suspicion of being a Communist and who became known as the father of China's space and missile programs, has died. He was 98.

    Qian, also known as Tsien Hsue-shen, died Saturday in Beijing, China's state news agency reported. The cause was not given.

    Honored in his homeland for his "eminent contributions to science," Qian was credited with leading China to launch intercontinental ballistic missiles, Silkworm anti-ship missiles, weather and reconnaissance satellites and to put a human in space in 2003.

    The man deemed responsible for these technological feats also was labeled a spy in the 1999 Cox Report issued by Congress after an investigation into how classified information had been obtained by the Chinese.

    Qian, a Chinese-born aeronautical engineer educated at Caltech and the Massachusetts Institute of Technology, was a protege of Caltech's eminent professor Theodore von Karman, who recognized him as an outstanding mathematician and "undisputed genius."
